Some lucky owners of the latest iPhone 5 have begun to regret their purchase. The fact is that the new device is made of aluminum - a rather flexible metal. So those who are used to keeping their CellPhones in the back pocket of their pants, the somewhat ‘flexible’ phones simply bent. So, this is when I ask the question: “How could it bend?”, as according to Apple, the screen is covered by tempered glass, which is scratch and it is extremely tough.
One of the main reasons that solar cells aren’t more efficient at converting sunlight into electricity is because much of that sunlight is reflected off the cell, or can’t be fully absorbed by it. A new sandwich-like material created by researchers at Princeton University, however, is claimed to dramatically address that problem – by minimizing reflection and increasing absorption, it reportedly boosts the efficiency of organic solar cells by 175 percent.
